To test the affinity of protein C with small molecules.

Technical difficulties:
Data obtained from MST showed poor affinity and low signal-to-noise ratio.

Solution:
The ITC method, which does not require fluorescent labeling or immobilization of the protein, was used to obtain the affinity.
The affinity values replicated the results from MST.
ΔH indicated that the binding reaction is exothermic, and ΔS indicated an entropy-reducing reaction, with the chemical stoichiometry of the protein and small molecule binding also obtained.
